This is not correct and the oversight places the leather industry and chemical suppliers to the leather industry under unwarranted suspicion. As far as the IUL can determine from initial enquiry, dimethyl fumarate is not used by any tanneries and has not been used by the tanning industry for the preservation of finished leather. In addition, the statement that dimethyl fumarate is ‘often used in everyday consumer products such as leather sofas and shoes’ appears to be a gross exaggeration and not an accurate depiction of the facts.

Readers should also not confuse the ‘DMF’ acronym which is sometimes used in relation to this issue with other chemistries that are more widely referred to as DMF – eg dimethylformamide and dimethyl furan.
